Specification of Letters Patent.

Fatented Feb. 6, Multa Application filed. June 9, 1915. Serial No. 33,010.

To all whom t may concern.'

Be it known that l, Louis HERZOG, a citizen of Switzerland, and a resident of Beacon, in the county ot Dutchess and State of New York, United States ot' America, have invented certain new and useful improvements in Jacquards, oi' which the following is a speciiication.

My invention relates to improvements in jacquards and more particularly. to jacquards for operating enibroidering machines. ln jacquards of this class there are provided `devices for producing movements of diii'erent extents, and these are coupled at each stitch operation with various devices for operating the tambour trame ot the embroidering machine, and these latter devices serve to combine the movements of different extents and to translate them into movements ot different directions so that many combinations may be obtained.`

Since all the tambour frame moving devices are not always connected with the movement producing devices it is customary to lock the tambour frame moving devices at all times except when they are selected for operation, to prevent displacement of the parts and to prevent erroneous results. This necessitates the unlocking of the selected devices so that they may be operated, and my present invention relates to the means 'ier controlling or causing these unlocking operations.

fin LT. S. Patent No. 528,632, there is shoiin and described a complete jacquard oi tie type referred to, and since .l have adapted my invention to a jacquard el' that type it will simplify this case to make cross reLt-ereiice to that patent; butit is to be dis- J understood that the present invenis not limited to a jacquard ol:` that type as it may be otherwise applied. ..."lie object of my invention is to avoid wear on the needle slides caused by the unlocking device, so as to prolong the lite ot' these slides and to avoid erroneous operation ot the parts as might happen where the continual friction ot' the unlocking device on the slides wears the latter away to such an extent as to cause the unlocking device to engage and be controlled by the wrong slide and thus unlock the wrong tambour Jrame moving devices.

Another object of my invention is not only te avoid wear on these slides by transferring the action to other parts, or by eliminating the friction to a considerable extent but also to control the unlocking devices Yfrom a diilerent part ot the mechanism than heretofore in order that the unlocking operations will inerrantly agree with the coupling operations.

Fig. 7 is an end elevation of shown in Fig. fi, and

Fig. 8 is a perspective view of the links which carry the locking members.

i have shown only such parts ot the coinplete jacquard as are necessary to an understanding o my invention. ris above stated, l have shown a jacquard of the kind set forth in U. S. Patent 528,632, by way ot illustration.

The shaft l is the main shaft ot the jacthe parts quard, and there are secured thereon the cams 2 and 8. There is a lever rocking on a shaft 7, journaled in bearings 8, one arm G, ci which lever has a roller 5 bearing on the cam 2, whereby this lever will be periodically rocked in accordance with the revolutions ot the main shaft.

The other arm i0, oi' this lever has links 13 ulcrumed t iereto one in each el the holes il. lt is to be understood that these links are arranged side by side, and each with an end fulcrumed to the arm l0 in a. hole ll, the same as in said patent. Since these links are 'fulcrumed at diiierent distances troni the axis of the arm l0, c., at dii't'erent distances from the shaft 7, they will reciprecated different extents when the lever ,is rocked, and the parts operated by these links will also be operated ditlerent distances Fach link 13 1s tulcrumed at one end to a vertical slide 14 by a bolt l5. The construcc edges they are tion shown in said patent comprises seven vertical slides lettered G1, G2, G3, Gt, G5, G, G7, and there may be seven such slides le in the present structure, all arranged to travel parallel to each other between the guides 16 on the base 9, and at their upper guided in the grooves in the top plate (not shown).

The rocking of the lever arm 10 as indicated in dotted lines, operates through the links 13 to reciprocate all seven slides 14, but each one to a ditlerent extent, according to the points at which the links are fulcrumed to the arm 10.

The mechanism for moving the tambour frame of the embroidering machine includes four slides 99, which are here shown horizontally disposed in parallel relation the same as in said patent, and they are preferably supported and guided by the same means as the slides L, L1, L2, L3 in said patent, with which they correspond. F rom these slides 99 to the tambour frame of the embroidering machine the same mechanisms may be employed as in the said patent and, since they require no modification they are not shown herein.

These slides 99 operate the movement combining devices and they are coupled to and uncoupled from the slides 14, in order that they may receive motion from the latter in accordance with the control of the jacquard card. These slides 99 require to be locked except when they are being moved by the slides 14, in order that they shall not be displaced and permit erroneous positioning of the tambour trame; and the present invention has to do with the mechanism for controlling the locking and unlocking of these slides or equivalent devices.

r he coupling of the slides 14 and 99 in various combinations is controlled from thel Jacquard card and this may be accomplished through the same mechanism as that shown in said patent, an example of which is herein shown.

The cylinder is the'card cylinder, corresponding to the part E2 in said patent. The jacquard card travels around this cylinder, the latter being rotated step by step. This cylinder is carried upon arms of levers which fulcrum on a shaft 68, the other arm, 71, oi which levers is ulcrumed at 73 to a link 72, which is connected and operated by the means shown in said patent. :it each rocking movement of the lever 71-70, the cylinder and card are moved toward and from the needles Gel and at each retraction the cylinder is turned sul'liciently to bring a new row of perlorations in line with the needles.

There is only one needle 6-1 showing in the presentdrawings, the others lying behind it. The number and their arrangement are fully shown and described in said patent. In that therewith may structure there are 2S such needles arranged in four groups with seven needles in each group and the same arrangement :may be here employed. The number or' groups corresponds with the number the number of needles in each group corresponds with the number of slides 14. F or simplicity, only one set of controlling` elements will be traced, since the others are merely duplications thereof, in so far as the present invention is concerned.

rlhe needles 6e are slidable toward and from the cylinder in grooves 64a, in the supports 63. The needle slides 62, one for each needle 6i, also slide in the grooves 6ta. The' needle has an angular end 66, which engages one of the supports 63 to limit its movement in one direction and this end is engaged by the downward extension 67 of the slide 62, so that rearward movement of the needle will cause a. similar movement ot the needle slide. Y

The needle slide has notches 7e? and 75 with which the locking pawl 76 engages, like the notches 0, o and pawl O in said patent. The pawl 76 engages in the notches 74 or' those slides which are displaced by the card and in the notches 75 of those which are not displaced, in order to hold all the slides against accidental displacement during their active periods. The pawl 76 is connected to the shaft 77 on which isiiXed an arm 7 8 which is rocked through the link 79, as `in said patent.

In the present construction the notches 02 of said patent, and the parts cooperating be omitted because the unlocking actionis here otherwise controlled.

Each needle slide 62 is connected by a link rod 60 having a projection 61 projecting therein, with a selector slide 44. rlhe latter is adapted to rock on its curved end and also to slide in grooif'es in the supports 475, the same as the slides j in the patent.

For each selector slide all there is a coupling slide 2l, comprising a horizontal portion A and a vertical portion B, which slides move horizontally as well as vertically in the grooves in the supporting rails 25 (four of the latter being shown in the drawings).

The selector slide blocks e6 on the coupling slide 24;, so that the former may reciprocate in relation to slide 24, but the latter will be lifted when slide il is rocked.

The end o1a the slide est has a lower notch Li7 and an upper notch 4S, which lie in Vadvance of each other. The jaw 49 is adapted to engage in the notch'T or with the solid portion near it, according to whether the slide is selected and advanced or whether it remains in Vthe position shown. In similar manner the jaw 50 engagesV with the top edge of the slide le or in the notch 48, according to whether or not the slide is adof slides 99, while Y le lies between the vanced. When these jaws are closed, the slides which have been advanced will be locked in the lower position and those which have not been advanced will be raised to the dotted line position and will control the coupling devices. The jaw 49 is fixed on a shaft 51, having an arm 53 thereon, and the jaw is fixed on a shaft 52 having an arm and both shafts are rocked by a forked link 55 connected to the arms. 'The lower end of the link is fulcrumed at 57 to a lever 56. rlhe other arm of the lever 56 has a roller 59 which engages the cani 3 on the main shaft.

There is a pawl 33 arranged to engage in the notches 31 of those slides lil which are raised and in the notches 32 of those which are not raised, and it serves to hold the slides in either position during their active period. The pawl 33 is fixed to the shaft 34, which latter has an arm 37. To the latter is fulcrumed a link 39 which is also fulcruined to a lever Ll1. The other arm of this lever has a roller which engages the cam 3 on the main shaft.

On the horizontal portion A of each coupling slide 2athere is a sliding block 23 which travels along the slide and from which depends a bracket Each block carries a depending` coupling rod 18, and in order that four rods 18 may be associated with each slide 14tthe rods 18 of four adj acent coupling slides Qd are brought into line and pass through apertures in the slide 1a.

Thus, there are four coupling rods for each slide 14, corresponding with the num ber of slides 99 which may be coupled with the slides 14. There are, therefore, 28 rods 18, controlled by the 28 needles 64. The grouping of the slides 24 is somewhat different than the grouping of the needles, due to the crossing of the link connections 60 in the manner shown in said patent, so that, instead of four groups of seven each, as with the needles, the slides 24: are arranged in seven groups of four each. This arrangement is not imperative to the use of my improvements, but it is thus described merely to illustrate a structure like the said patent as an example.

The several rods 18 are of different lengths and at the lower end each is connected with and adapted to raise a longitudinal bar 19 which is movable vertically but not horizontally in grooves in the brackets '2O carried upon the slides 14. The slides 99 each have forwardly projecting bars 98 lying just above the bars 19, and these have recesses 109 on their under sides to Vreceive the projections 191 on the bars 19. Then a bar 19 is lifted by a rod 18 its projection 101 will enter a corresponding recess and thus couple a slide 1a and a slide 99, so that the latter will move with the former when it is reciprocated by the lever G--10.

The mechanism thus far described correl spends with that of said patent.

The tops of the vertical portions B of the coupling slides 9st are curved at 94 soinewhat in the shape of an S, but the curves are alternated; that is, the curve on two ad jacent slides is directed forward and on the next two adjacentslides .it is directed rearward, as shown in Fig. 9; this arrangement extending to all the slides Qil.

In the side plates 35 of the jacquard there `are arranged the four shafts 83, 84 and 85,

86, disposed in upper and lower planes. These several shafts have flat portions Y to which are attached by means of screws 82 the four plates 27, 28, Q9, 30, which latter correspond in number with the slides 99.

4These plates, 27 to 30, have projections 27, 28', 29, 30', which have contact with the slides 211 and, owing to the curve 24 this contact is a rocking one and therefore there will be very slight friction and wear. The projections 27 on the plate 2T extend forward and there is one project-ion for thc first slide 2d in each of the seven groups.`

The projections '27/ on plate 27, therefore, are adapted to be acted upon by any slide 211, which controls a rod 18 which is adapted to couple any slide 1l with a particular slide The projections 2t on the plate 98 are on a lower plane to those on plate 27 and to correspond with this the slides 2l which operate on the plate 28 are somewhat shorter than those which operate on 97. The projections 28 on plate :28 (seven in number), are acted upon by the slides 24C adjacent those acting on plate 27 and they comprise all the slides which control the coupling of any o'l' the slides 14: with a particular slide The plate 99 has projections 29 extending in the opposite direction to those on plates 2T and 28 and these are acted upon by the slide S24: in each group adj acont those which act on plate 28. Thus, plate is actuated by any of .the slides lll which control the coupling of a certain slide 99. The plate 39, on a lower plane to 29, has projections 39 which are acted upon by the remaining slides corresponding with the remaining slide 99.

)n each shaft 83, 8l, 85, 89there is secured a lever arm 89, two of which project forward and two rearward. Each of these lever arms supports a plate 91 through the connecting link 90. rFliese several plates 91 are movable vertically in grooves in the supports and are shown as arranged in line with each other and with the portions B of the slides The plates 91 are of different lengths, so that their lower ends terminate according to the positions of the different bars 98 of the slides 99; and the plates are preferably provided with recesses 31, 39, corresponding with similar recesses in the slides ii s this will raise a bar plates will be locked periupper or lower positions by lone of the plates 91.V On each bar 98 of a sliding frame 99 there is an engaging member, here shown as a block 9T, and on the lever arms 94 there are engaging members 96 which engage the blocks 97.

Operation: When the parts are in the psitions shown in F ig. 1, each of the slides 99 is locked against displacement by the block 96 lying in front of the block 97 and the slides cannot be moved until they are unlocked. They will only be unlocked if they are selected for coupling to the slides 14 and if they are not so selected they will remain in locked position, If, therefore, the needle 64 shown in the drawing strikes a solid or unperforated portion of the jacquard card when ,the cylinder is reciprocated, this needle, and its slide 62, will be moved back, and this will move the slide 44 with which it is connected. IVhen the jaws 49-50 close, this particular slide 44 will be clamped in its original or lower horizontal position and no selection of a coupling element will be effected by it. Neither will it operate any of the unlockingl devices.

But should this needle 64 be in line with a perforation in the card it will not be moved back, and neither will the slide 44. When the jaws 49, close, the slide 44 will be swung up to the'dotted line position, it being understood that the pawl 33 is disengaged from the notches at this particular moment. The slide 24, engaging the blocks 46 will lift one of the coupling rods 18, and 19 to carry a projection 101 into a recess 100; and thus one of the slides 99 will be coupled with one of the slides 14, to be moved one stroke forward` and back with the latter. The slide 24 when it moves upwardly in this selecting or coupling operation, will engage one of the projections on the plate 27 and it will rock the shaft 83. This will lift one of the plates 91, rock one of the levers 94 and carry its block 96 out of the path of the block 97 on the corresponding slide 99. This latter' slide, is, therefore, unlocked, and it is also coupled with one of the slides 14 for movement therewith. The same shaft 83 and the unlocking parts will be operated whether only one or several corresponding slides of the different-groups is or are operated. There are twenty-eight slides 24 controlling the coupling, but there are only four slides 99 to be unlocked, so that .seven slides 24 are adapted t0 operate each lever 94.

If any other slide 24 of another group, or

if Several of another or other groups operate a coupling device they will also operate their respective unlocking devices.

When the slides 14 and any slides 99 which have been. coupled thereto, have made. their stroke forwardly and back, Vthe slides 24 and the coupling devices connected therewith will be returned to their starting or initial positions f and the lowering of the slides 24 will also permit the plates 27-30'to rock back to their initial positions; and thus the blocks 96 which were unlocked, are returned to locked position, ready for the succeeding operation. sure the return of the locking devices I have shown springs 102 having one end connected with a hook 103 on each of the plates 91, and the other end connected with hooks 104 on one of the supports 25; so that the springs pull down the plates 91.

From the above it will be seen that the locking device causes no wear on the needle slides 62 as it may be entirely independent thereof. There will be no appreciable wear on the slides 24 where they strike the projections of the plates 27-30 and it will be unimportant because Aany slight wear will not cause an erroneous operation of the parts.

Furthermore, it is obvious that if any slideV 99 is coupled with a slide be unlocked.

In describing the invention in connection with this form of jacquard I do not intend to be understood as limiting the same to this particular embodiment.
